Specification of Letters Patent.

Application filed October 19, 1909.

To all whom it my concern: I

Be it known that we, Anon G. Snimnc and EDWIN G. SnBnnc', citizens of the United States, residing at Racine, in the county of Racine and State of \Visconsin, have invented certain new and useful Improvements in Drilling-litachines; and we do hereby declare the following to be afull, clear, and exactdesoription of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same.

Our invention relates to new anduseful improvements in drilling machines and-more .forcing the drills out of the housing by departicularly to that class adapted to be used for constructing tunnels, drilling ores and .various other purposes and our object is to provide suitable drilling mechanism and mounting the same upon trucks.-

A furthenobject is to provide suitable drills and housingstherefor.

Av further object isto provide means for yieldingly mounting the drills and housings therefor. I

A further object is to provide means f0 ivering a blow thereto.

A further object is to provide rotating means for carrying the drills and housings.

A furtherobject is to provide suitable gears for rotating and operating the drill carrying mechanism.

A further object is to provide means for raising and lowering one end of the drilling mechanism. 1

A further object is to provide means for swinging one end of the drilling mechanism laterally.

A further object is to provide means for propelling the trucks upon which the drilling mechanism ismounted and a further object is to providemeans for operating and controlling, the movement of the drilling mecln anism. c

Other objects and advantages will be here inafter referred to and more particularly pointed out in the claims.

In the. accompanying drawings forming part of this application, Figure 1 -is a top plan viwof the drilling mechanism complete. Fig. 2 is a side elevation thereof, showing parts of the device in section. Fig. 3 is a sectional view as seen on line 33.

Fig. 1. Fig. 4 is a diagramn'iatic view of the supporting trucks for the drill. showing the manner of applying power thereto.

form housin Patented Nov, 22,1910. Serial No. 523,451.

Fig. 5 is an enlarged detail sectional. view showing the manner of mounting the drills, and, Fig. 6 IS an elevation partly in sectionof one of the drill housings and parts of the wheel to which it is attached. Fig. 7 1s a vertical section of the machine taken on line 7;7,-Fig. 2.. Fig. 8 is a fragmentary 'slde elevatlon of the machine showing a The axles are driven from a motor or similar device 7, through which extends a shaft 8, the ends of the shaft having bevel gears 9 thereon, which mesh with similar ears 10 carried by shafts 11 and.12, sai having worms 13 and 14, respectively and the worms in turn mesh with cars 15 and shafts 16, respectively on'the ends 0 the axles 5 and 6.

By this construction it will be readily seen that when power"is'-applied to the shaft 8, the axles 5 and 6'will be Fo'tated' and the drilling mechanism caused to travel over the track-way 17 and it will further be seen that the worms and gears cotiperating therewith will act as brakes and hold the trucks against movement on the track-way.

Mounted upon the .trucks 1 and 2 is a frame 18, a portion of said frame being cylindrical and formin a bearing for a tubular sleeve 19, one en of the sleeve having agear 20 fixed thereto, while the opposite cnd is provided with'a cross head 21.

Extending forwardly from the cross head 21 are ears-22, said ears havin flanges 23 to'securely brace the. same and extending transversely throu h said cars is a shaft 24 and on said shaft 1s mounted a drill carrying wheel 25, said .wheel being formed in two sections and secured together by means of bolts 26 or other suitable devices.

The meeting faces of the two sections of the wheel are provided with semicircular channels 27, in which are adapted to fit shields 28, said shields being adapted to for the drills 29.

The shiel s are adapted to move longitudinally through the channels and are yieldingly held therein by means of a spring througha-slot 31 in the wall of" the shield and enter a groove-32 in the body of thedrill, said groove 32 being greaterinlength than the normal length of the spring, whereby the drill may be moved out of the shield without affecting the tension of the spring. 1 The spring 30 is introduced into the slot and groove through an opening-33 in one section of the wheel25'and is held therein by providing a plug 34:,- which is' adapted to fit said opening, the plug having a c evis 3-5 attached thereto which passes through the spring 30 fromend to end thereof, thus permitting the spring to be depressed,-while at the same time is securely held seated in its respective slot and groove.

The plugs 34: are held seated in the openings 33 by attaching one end of a spring 36 thereto, the opposite end of-said. spring-beingattached to the drill :wheel'25 and so arranged as to direct pressure against said plug at all times.

The drills 29 are yieldingly held within the shields 28 by means of springs 37, said springs being -entered throu 11 slots "38 formed in the wall of-the shield and entered into grooves 39- formed in thedrills 29, said slot and groove being of a length equal'to the normal length of the spring, while the ,depth of the groove 39 is such as to extend the spring substantially one-half its diameter in the shield and the other half in the groove. 4

The shields 28 projecta distance beyond the periphery of tlie wheel 25 and'have attached to their outer ends heads 40,-the faces of which are voval, 'whereby they Willv engage and pass over uneven surfaces, the outer ends of the drills resting. substantially flush with the oval faceof the heads, whilethe inner ends thereof project beyond the shields and enter a cavity 41 in the interior of the wheel'25 and around the axial center thereof. v

Located within'thecavity 41 is a disk 42, the peripheral edge of said disk having. a recess 43 therein, in which are positioned hammers 44, the trunni0ns' l5 of said hammers being extended through elongated slots 46 formed in the disk 42, said slots extending through the walls formed-by the recess 43. v

The hammers44 are. circular in cross sec-' tions and are adapted to strike the inner ends ofthe drills 29 and force the same outwardly throu h the ends of the shields 2S and in view of the momentum resulting from rapidly rotatingthe disk 42, the truunions'will move to the outer ends of the slots i6 and move thehannn'ers in )ositionthe shafts 51 and 52 and gears attached '78 and 79, respectivelyfsaid shafts being mers were stationary, owing to' the great! force with which .the hammers are brought.

into engagement with the drills.

When the heads iO are out of engagement with the wall of the tunnel or the object being drilled, the drills will remain out of the. path of the hammers so that the" drills will not be operated, but as soon as the heads pass into engagement with the wall, the shield and drill is moved inwardly and the inner end of the drillbrought into the path of the. hammers so that'the drill will be" forced out of, the shield and into the object in engagement} with the head 4:0 and in View of the springs 30 and 37, the drills will be I the blow has been deliyered.

The' disk 42 is rotated very rapidly, which will result in causing the drills to be con immediately returned into the shields after 'tinuously driven intotheobject at the outer and 52, respectively, said shaftsextending from the shaft 24 to the cross head, bearings 53 and 5 1 being provided on said cross head to receive the ends of the shafts while 7 the opposite ends of said shafts are extended through bearlngs 55. and 56, respectively, on

the ears 22. y

' The shafts 51 and 52 are rotated by placing thereon cogs 57 and 58, respectively, which mesh with a cog 59 on the end of'a tubular driving shaft 60, said driving shaft extending horizontally through the sleeve 19.

The opposite-end of the shaft 60 from that occupied by the gear 59 has a gear 61,

which meshes with a gear-62 on a worm shaft 63 and it will be readily seen that when said worm shaft is rotated, the tubular shaft 60 will be likewise driven, which will result in rotating the disk 42 through thereto. a i The wheel 25 is rotated independently of the disk 42 and preferably at a different speed, a sprocket (34 being attached to one section of the driving Wheel 25 around which extends-a sprocket chain 65, said chain also extending around a sprocket 66 carried by a stub-shaft 67, said shaft being mounted upon one. of. the ears 22.

Fixed with the sprocket 66 is a bevel gear G8,-which meshes with a similar gear 69 on the end of a shaft 70, said shaft extending through the tubular shaft 60 and beyond each-end thereof. The opposite end of the shaft 70'from that engaged by the gear 69 is engaged by a car 71, which meshes with reversing gears 72 and 7 3 mounted upon shafts 7 4 and :7 5, respectively, said shafts being mounted in suitable brackets 76, 77 and extended in a horizontal position.

Extending horizontally between posts 80 and 81 is a gear shaft 82, on which is mounted a worm gear 83, with-which engages a worm 84: carried by the shaft03, and said worm and gear are employed for operating the shafts-74 and 7 by mounting the bevel gears 85 and 86 on the-shaft 82, which mesh 1 with similar gears 87 an d 88 on the shafts to be geared to the gear 71 and to readily accomplish this result,.the hubs of the gears 72 and 73 are, provided with clutch faces 89 and .90, respectively, with which are adapted to engage clutches 91 and 92 mounted on the shaftsfl and 75, said clutches being slidably mounted on said shafts and feathered thereto.

. sary for the opposite clutch to be disengaged therefrom and vice 'versa. when itis desired to rotate the wheel in the opposite direction. The sleeve 19 is also adapted tobe rotated, whereby the parts carried by the cross head 21 will be bodily sleeve and to accomplish this result, gears 93 3O rotated with the and 94 are attached, respectively, to the shafts 74 and 75 and are provided with clutch faces. 95 and .96, with which are adapted to engage clutches 97 and 98 on said shafts, said clutches being feathered to said shafts and caused to rotate therewith, said clutches being operated inconjunction with the clutches for he reverse gears and as the reverse gears 93 and 94 are in mesh with the gear 20, the sleeve 19 will be readily operated thereby. In addition to rotating the drill wheel and forcing the drills into engagement with the walls of the tunnel, the drill carrying end of the frame 18 may be raised or lowered to enlarge the dimensions of the tunnel byrotatably mounting an interior-1y threaded nut 99, which is rotatably mounted on the truck and in the threaded opening of saidnut is introduced an exteriorly 'and interiorly threaded stem 100 of a gear 101 and as the drill carrying end of the frame 18 rests upon said-gear 101, it willbe readily seen that when said gear is rotated in opposite directions, saidend of the frame will be raised or lowered. The same end ofthe frame 18 may be likewise swung laterally by entering a stud 102 into the stem of the gear 101, the upper end of which stud projects through an opening 103, in the frame 18 and by placing said stud ecce'ntrically ofthe axis of the gear 101, the rotation of said gear will move the forward end of the frame laterally, whereby an oblong or substantially square opening may-be produced.

A pair of shafts 104 and 105 is mounted .115 and 116, respectively,

spectively, which mesh with the worm 108 on the drive shaft '63. Said shafts are formed in sections and the sections connected by means of sleeves or. slip couplings the connect-ion between the slip couplings and the shafts being by means of universal links 117 and 118, respectively. The lower sections of said shafts are provided respectively with the gears 110 and 111 which mesh with the teeth of the nut 99 and said shafts are also provided with additional gears 119 and 120,

respectively, said latter gears meshing with the gear 101. The gears 110, 111, 119 and 120 are all loosely mounted on the shafts 104 and 105 and as said shafts are rotatingcontinuously, it'will be seen that the same have normally no effect on the gear 101 and the nut 99. To cause said gears to have effect on said nut and gear, however, or in other words, to cause the same to be rotated either together or separately, I have provided the cone clutches 112 and 113to cooperate with the gears 119 and 120, respectively, and the clutches 121 and 122 for the gears 110 and 111, respectively, said clutches being securely held to the lower sections of said shafts and adapted to be moved vertically on said shafts into and out of effective engagement with said gears.

It is often desirable in the operation of a machine such as this to enlarge the tunnel which is being made or change the course of the machine and such operation is performed by throwing into and out of effective position, said clutches which, in turn, cause the gears on the shafts to cooperate with the gear 101 and the nut 99, as the case may be. By throwing into effective position, the clutches 113 and 122 and the throwing out of the clutches 112 and 121, as indicated in Fig. 7 or vice versa, the head of the machine will be swung laterally by the rotation of the gear 101 and the nut 99, upon which said head is eccentrically mounted. without raising or lowering the same. By throwing the clutch 113 in-and moving'all others out of effective position, the head of the machine will be raised and at the same time swung laterally and by throwing the clutch 112 in and moving all others out, the head of the machine will be lowered and at "the same time swung laterally. Vith the clutch 121 thrown in with the others moving out, the machine will be raised without the lateral movement and vice versa when the clutch 121 is thrown into effective position and all others moved out, the,machine will be lowered withoutlateral movement. With the clutches 113 and 121 thrown inand the others moved out, the machine. will be raised at double speed with the normal lateral movement of the same'and vice versa when the clutches 112 and 122 are moved in. and the others.

out, the machine will be lowered at double speed with normal .lateral movement.-

Hence, itwill be seen that the machine may mentwithout either raising or low'ering'the same, which provides for all ,ditliculties which may be encountered in tunneling."

I have made no provision for the levers which may'operate the various clutches, as

done by the provision some conventional form of motor 114.

described, but as this formsno extremely essential part of the invention, the'usual or any preferred form may be used and it will be seen that in view of the lateral movement which is given the head of the machine, it is absolutely necessary to'providejtheshafts 104: and 105 with flexible intermediate connections which has, in this instance, been of the slip couplings and universal joints. v

The power for operating the several parts with the exception of the supporting trucks is applied to theishaft63 in any suitable manner as by placing a gear.wheel109 thereon and having the same rotated through By. mounting the drills in-the manner shown and providing the hammers for op-' crating the same, it will be readily seen that the drills will bedriven into the soil, rocks, etc., in the path of the drills when the heads of the shields are in engagement with the soil, etc. and said drills will be operated with great rapidity. It will likewise be seen that by rotating the drill carrying parts, a

circular tunnel may be formed and further by shifting the front portion of theframe carrying said parts laterally, a square or oblong opening may be formed.
